ARGAND GAS-BURNER SPECIFICATION forming part of Letters Patent No.383,338, dated May 22, 1888.

Application filed January 31,` 1887. Renewed April 19, 1888. Serial No.271,125. `(No model.)

di To all whom it may concern:

which will be more fully hereinafter described,

and pointed out in the claims.

One object of my invention is to provide a gas-burner which will insurecomplete and perfect combustion of gas, and by suitable means cause thesame to produce a steady and brilliant light.

A further object of my invention is to provide a gas-burner which isadapted to be attached to ordinary xtures in suoli a manner as toprevent the heating of said iixtures by the ignited gas in the burner.

I attain these objects by the burner illustrated in the accompanyingdrawings, wherein like letters of reference indicate similar parts inthe several views, and in which-V Figure l is a vertical central sectionof my Fig. 2 is a detail top plan view of the conical perforatedthimble. Fig. 3 is a transverse vertical section of the same. Fig. 4shows a detail top plan view of the twopart nipple or burner-tip and thecontinuous annular slot. Fig. 5 is a detail top plan View of thegas-chamber adjusting-ring. Fig. 6 is a detail view in verticalcross-section of the gas-chamber adj usting-ring and the interposedperforated ring-plate. Fig. 7 is a detail view in cross-section of theheat-non-conducting B, constructed of wood or other heat-non-conductingmaterial, is connected to the joint C between the burner proper and thefixtures, and is provided with metallic end caps or bindings, A. Theunion B is preferably made in the shape shown in Fig. 7, but may beconstructed in any other suitable form. As shown, it consists of a ringof wood having depressions in its outer surface near its ends, which arecovered by metallic caps A, constructed to conform to the curvature ofsaid ends, their outer edges resting in said depressions and theirinner-edges struck upto form a lining for the ends of the` bore of saidunion B. The latter-named parts of the caps A are screwthreaded, so asto provide for the attaching of said union to the fixtures and burner.In Fig. 8 one of these caps A is shown in detail, the generalconstruction of the same being fully illustrated thereby. The union Bconnects the joint C with a conical-.shaped tube, E, said tube beingscrew-threaded on its lower end to engage with the said union.

D is a bracket or support of circular shape, with an opening in itscenter, through which the conical tube E passes. The lower inner face ofsaid bracket is provided with a female screw, which engages with theupper screwthreaded portion of the tube E, thereby bringing said bracketin contact with the flange c, which forms a rest for the same andrigidly holds it in place. A series of hollow radial arms, S, extend outfrom said bracket and support an annular rim, d, which is provided withscrew-threaded portions on its upper, inner, and lower outer sides, towhich is secured a cylindrical chamber, T, which extends entirely aroundsaid portion d, and is provided with a closely-fitting nipple orburner-tip, K, which is inserted in its upper end and projects somewhatabove it, where it is provided with a continuous slot, k, the saidnipple or tip being constructed in two parts and supported on the innerand outer walls of the said chamber T by flanges k, projecting outwardlytherefrom, which rest on the top of the walls of the said chamber.

Immediately under the nipple or tip K a perforated thin metallic plate,K', is interposed between and held in position by the walls of thechamber T. Under the plate K a heavier plate, K", is provided, which isalso IOO constructed with apertures and held by the 'walls of thechamber T in a manner similar to the plate K. These two plates K and Kmay be securely fastened in the said chamber T in their desired positionby any well-known mechanical means. The plate K2 is adapted to keep thewalls of the chamber T at an unvarying and equal distance apart, therebyholding them in perfect relative adjustment to each other, and the plateK is for the purpose of equally distributing the pressure of the gas tothe fiame of the tip or nipple K.

Surrounding part of the conical tube E is a cylinder, I, which issecured at its lower end to the central portion of the bracket D. Thiscylinder or tube I extends upward above the burner-tip K, and has aflaring hollow chamber, L, secured thereto by screw-threads on its outerlower end, which engage with like threads on the inner surface of thecylinder I, thus leaving the top of the said cylinder to form a shoulderor bearingsurface. The hollow chamber L has a downwardly-extendingtubular neck, l, and upper flaring portion, extending out to a pointdirectlyv over the burner K, and a top flat portion provided with a lughaving a nick or cut therein for the reception of a screw-driver,whereby the said part may be secured in the cylinder I. The tube Eextends upward into the chamber L, the sides of which pass up on agradual incline, and ending about the central portion of the saidcharnber L. The chamber L is surrounded by a non-fusible defiector, M,which may or may not be constructed to conform to the shape of the saidchamber, but preferably of the form of an inverted frustum of a cone,and is construct-ed of kaolin, asbestus, orany other suitable singlematerial or combined materials, being securely held in place upon theupper end ofthe cylinder I by having its lower end resting on said upperportion of the said cylinder. The tubular neck Z of the said cylinder Ipasses through an opening in the lower end of the deflector, which isconstructed of such diameter as to closely fit said tubular portion orneck, so that when the said chamber is secured to the cylinder I it isforced down until the detlector is firmly held in connection with thecylinder I, the base of the flaring portion of the chamber L resting onthe inner portion of the deflcctor M at the top of the lower openingthereof. As will be seen, the deflector M is extended out a greaterdistance than the chamber T, thereby presenting a larger surface for theflame to iinpinge against. A small space is left between the outersurface of the flared sides of the chamber L and the inner surface ofthe defiector M, to prevent the burning-out of the walls of the saidchamber during the highly-incandescent state of the said deflector M.

F represents a series of supports or arms attached to the bracket D inany suitable manner, and supporting on their outer ends a gallery, G, onwhich is secured the globe-holder H. An air defiector or thimble, J, ofwellknown form of construction, is also placed on said supporting-armsF, being retained in posit-ion thereon by an outwardlyextending flangeconstructed on its lower edge, which flange is placed in the angularportion of' the gallery G, upon which the globe N rests. The spacebetween the lower edge of the deflector J and the chamber T is providedwith a perforated plate, O, through which the air passes as it is drawninto the burner, and by virtue of said perforations the current of airisdivided and passes into the burner more steadily and with less pressurethan is usually the casein burners of this class.

Between the outer surface of the cylinder I and the inner surface of theinner wall of the chamber Taperforated thimble,P, is mounted, and restsat its base upon the top of the series of hollow radial arms S,extending at its top close around the cylinder I, and extending outwardat the bottom thereof to the inner wall of the chamber T. This thimblePis provided with a series of apertures, p, which, in consequence of theconical form of the said thimble P, are arranged in spiral order, andact to nely divide the current of air passing therethrough, and adaptingit to bc more readily distributed against thc flame produced by theburning gas which exudes from the apertured nipple or tip K, mounted onthe top portion of the chamber T.

In Fig. 9 the same construction of burner is illustrated, as heretoforedescribed, with certain modifications of construction of some of itsparts. In this instance the tube E extends onlypartially up through thecylinder I and allows the gas to escape therethrough below the lowerportion of the neck Z of the chamber L; but I make no claim herein tothis arrangement of said tube and cylinder, as the same forms a portionof the invention constituting the subject-matter of an application forLetters Patent filed by me January 10, 1887, Serial No. 223, 886. Thenipple or tip K in this form of burner is constructed of a single bentpiece of metal provided with a series of perforations, no perforatedplates K and KZ being used, the gas passing directly into the nipple ortipK. In this construction the thimble P is dispensed with, and thecurrent of heated air is allowed to pass in an unbroken current to thefiame and not separated, as hereinbefore described, by the perforatedthimble P. When the gas is turned on by the key in the fixtures, itpasses through the joint C into the conical tube E, and from thence upinto the chamber L, and when it reaches the top thereof it is deflectedoutward and downward onto the inclined sides thereof and passes into thecylinder I, and from thence out through the radial arms S into thechamber T, where it ascends and escapes through the burner K, at whichpoint it is ignited. When the gas is ignited, the flame produced isinclined slightly inward by reason of the current of air coming upthrough the thimble J and impinges against the defiector M, which,

being of non-fusible material, soon becomes heated and Very brilliant,and in turn adds to the brilliancy of the ignited gas. The draftproduced by the combustion of the gas draws the air, which will havebecome heated, in finely-divided currents, up through the perforatedthimble l3 to the inside of the flame, andtherebyincreasesthecombustion. Bythisheating ofthe deflector M the wallsof the hollow chamber L,which, as above stated, is placed in closeproximity and entirely surrounded by the said deiiectonare heated toahigh degree,there by heating the gas, which in turn transmits heat tothe cylinder I, arms S, and chamber T, which in turn heat the gas andair passing therethrough. By this heating of the gas a more perfectcombustion is obtaincd,and by the heating of the said parts the airwhich passes into the burner is also heated, and in this condition ismore quickly and readily mingled with the gas, thereby causing a moreperfect and rapid combustion of the oxygen of the air and the gas. Itwill thus be seen that a great degree of heat is confined to thedifferent parts of the burner, which in' other burners is conducted tothe iiXtures, which is objectionable, and which objection I practicallyovercome by means of the union B, constructed of heatnon conductingmaterial, thereby retaining the heat in the burner, which wouldotherwise be absorbed by the ixtures, and thus aiding in a more perfectworking of the burner.

It is obvious that many minor changes in the construction andarrangement of the parts could be made and substituted for those shownand described without in the least departing from the nature andprinciple of myinvention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, :is-

l. In an Argand gas-burner, the combination of the bracket provided withradial bollow arms, the conical tube screwed centrally upon saidbracket, thc cylinder surrounding substantially as and for the purposespecified.

3. In an Argand gas-burner, the combination of the conical tube, thecylinder surrounding said tube, the hollow chamber mounted thereon, thenon -fusible conical-shaped dellector surrounding said hollow chamber,the bracket having hollow arms connecting and supporting theburner-chamber, the perforated thimble mounted between theburner-chamber and the cylinder surrounding the central tube, and theouter thirnble or air-conductor and defiector, substantially asdescribed.

4. In an Argand gas-burner, the combination of thc union B, having capsor bindings A,a conical tube, E, connected thereto, a cylinder, I,surrounding said tube, a hollow flaring chamber, L, a non-fusibledefleetor, M, surrounding chamber L, a bracket, Dhaving hollow radialarms S, supporting and connecting .the chamber 'I' with the cylinder I,a suitablyapertured tip or burner, K, inserted in the chamber T, and asuitable globe-support, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
